Abstract
AIMS
To evaluate the effects of cesarean section (CS) on the prevention of mother-to-child transmission (MTCT) of hepatitis B virus (HBV) among hepatitis B surface antigen (HBsAg) positive pregnant women.
METHODS
A prospective cohort study was performed on HBsAg-positive pregnant women who delivered from June 2012 to March 2017 at Wuhan Medical Care Center for Women and Children in Wuhan, China. Logistic regression models were used to examine the associations between mode of delivery and the presence of HBV MTCT.
RESULTS
A total of 1384 women paired with 1407 infants were enrolled. Our study showed that the incidence of HBV MTCT was 1.0% (14/1407) in infants born to HBsAg-positive pregnant women. We observed that the infants born by CS had a smaller percentage of HBV infection than those born by vaginal delivery (VD) (0.5% vs 1.7%, P = 0.043). In the fully adjusted model, CS was significantly associated with a decreased risk of HBV MTCT (OR = 0.26; 95% CI: 0.07-0.95; P = 0.042).
CONCLUSION
Our data confirmed that CS has a protective effect on early MTCT of HBV. CS for HBeAg-positive mothers with high viral load could reduce risk of MTCT and may become a new preventive measure of HBV MTCT through research on its risk-benefit assessment.
